数字经济如何影响中国经济高质量发展?——基于创新要素配置的视角

How does the Digital Economy Affect the High-quality Development of China's Economy?--Based on the Perspective of Innovation Factor Allocation

在经济新常态下,迅速发展的数字经济不仅是经济增长的重要因素,也是推动经济高质量发展的关键动力。从理论层面探究了数字经济对经济高质量发展的直接影响、间接影响和空间溢出效应,利用2014—2022年中国30个省(区、市)的面板数据实证分析了数字经济发展水平对经济高质量发展的影响;进一步通过内生性处理、变量替换、样本子区间估计以及缩尾处理等进行模型稳健性检验,并开展区域异质性分析。研究发现:数字经济对经济高质量发展具有显著正向影响;创新要素配置在二者之间起部分中介作用,且随着创新要素配置水平的提升,数字经济对经济高质量发展的影响呈现出边际效应递增的非线性特征;数字经济与经济高质量发展之间存在明显的空间正向关联;数字经济对经济高质量发展的影响效果存在区域异质性,作用强度从东部、中部地区向西部地区逐渐减弱。因此,要以新发展理念为指引,合理布局发展数字经济,结合数字技术优化创新要素配置,充分挖掘经济高质量发展新动能;针对区域之间发展不平衡问题,政府部门应加强宏观调控,推动区域协调均衡发展。

Under the new economic normal,the rapid development of the digital economy is not only an important factor for economic growth,but also a key driving force for high-quality economic development.The article explores the complex impact of the digital economy on the high-quality economic development from the theoretical level,and measures the digital economy,high-quality economic development,and the index of the innovation factor allocation using the entropy value method with the panel data of 30 provinces in the period of 2014—2022,and conducts empirical research on the impact effect of the level of development of the digital economy on the high-quality economic development by constructing the fixed-effect model,me-diation effects model,panel threshold model,and spatial space Durbin model.In addition,the ro-bustness of the model was tested through endogeneity treatment,variable substitution,sample subinterval estimation and reduced-tail treatment,and regional heterogeneity analysis was con-ducted.It is found that the digital economy has a significant positive impact on the high-quality economic development,and there is a partial mediating effect of innovation factor allocation be-tween the two.As the level of innovation factor allocation increases,the impact of the digital economy on the high-quality economic development shows a non-linear characteristic of in-creasing marginal effect.At the same time,the digital economy has a positive spatial spillover ef-fect on the high-quality economic development,and promotes the high-quality economic devel-opment of neighbouring regions.Further analysis reveals that the impact of the digital economy on the high-quality economic development varies in different regions,gradually weakening from the eastern and central regions to the western regions.Therefore,it is necessary to take the five concepts for development as a guide,rationally layout the development of the digital economy,optimise the allocation of innovation factors in combination with digital technology,and fully tap the new power of high-quality economic development.The unbalanced development among re-gions requires macro-control by government departments to strengthen regional coordination and balanced development.
